Transpiration water is transported in plants, from the roots to the leaves, following a decreasing water potential gradient transpiration, or loss of water from the leaves, helps to create. The rate of transpiration depends on several environmental factors such as light, humidity, temperature, and air movement, while the rate of evaporation depends on the water potential.
